Lab million gallons of runoff from carrying pollutants into the ecosystem each year (about 98 percent of all stormwater). Reclaimed water from the City of San Francisco will be used to flush the toilets, reducing the use of potable water for wastewater conveyance by 90 percent. Low-flow fixtures and the use of reclaimed water will reduce overall potable water use by 78 percent. Saltwater for the aquarium is piped in from the Pacific Ocean, minimizing the use of potable water for aquarium systems. Nitrate wastes are purified with natural systems, ensuring that aquarium water can be recycled. LIVING Recycled Building Materials More than 90 percent of the demolition waste from the old CAS structure was recycled. Concrete and steel were reused in local roadside construction projects and recycled onsite, respectively. At least 50 percent of the wood in the CAS facility was sustainably harvested and certified by the Forest Stewardship Council. Recycled steel was used for 100 percent of the building’s structural steel; the steel includes 95 percent recycled content. The Bonded Logic insulation in the building’s walls is made from recycled blue jeans and contains 85 percent post-industrial recycled content. All concrete contains 30 percent fly ash, a by-product of coal-fired power plants. It also Green recognitions for FrameGuard® wood: Through all aspects of design and construction, CAS will strive to achieve the highest possible rating from the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) Rating System: LEED Platinum. CAS’ rating is expected to be awarded by the end of 2008. In recognition of this commitment to sustainable design, CAS was selected as the North American winner of the silver Holcim Award for Sustainable Construction in September 2005. The competition, organized by the Holcim Foundation for Sustainable Construction in collaboration with ﬁve of the world’s leading technical universities, promotes sustainable approaches to the built environment. CAS was also awarded the Environmental Protection Agency’s (EPA) regional 2006 Environmental Award in recognition of the new building’s sustainable design. The EPA received more than 160 nominations in 2006; CAS was one of 39 recipients to be selected. od– meGu si ant with Fruard coated molddreWstlmanwoed iz Win FrameG a o elope ® ® MOd D. od.
